BARBED FENCE-STRAP.

SPECIFICATION forming par@ of Letters Patent No. 258,88*?, dafeavaune e,1882.

l Application tiled February 4, 1882. (No model.)

To all-whom tt may concern Be it known that I, JAMES CARPENTER, ofMoravia, in the county of Cayuga, in the State ofNew York, have inventednew and useful lmprovements in Barbed Fencestraps, of which -thefollowing, taken'in connection with the accompanying drawings, is afull, clear, and exact description.

The nature of this invention consists in a novel construction of ametallic strap having enlarged or re-enforced edges and transverselycrimped or corrugated surfaces and barbs pressed laterally out of saidre-enforced edges alternately at opposite sides of the strap and fromthe convex side of the corrugations, said strap being secured edgewiseon the fence and presenting straight or unbroken top and bottom edges.The strap constructed as aforesaid retains its fullwidth throughoutitslength. The barbs pressed or st ruck out of the enlarged edges of thestrap, and being nearly or quite at right angles to the planethercof,stitl'en the strap, and the projection of the barb from the convex sidesof the corrugation renders the same more prominent, and thus requiresless length of the barb. lhe corrugatons allow the strap to expand andcontract under the variations of the temperature of the Weather, andthus prevent excessive sagging, as well as undue tension of the strap.

Thenveution also consists in a novel method of forming the aforesaidbarbed strap, all as hereinafter fully explained.

In the accompanying drawings, Figure l is front view of my improvedbarbed fence-strap. Fig. 2 is an edge view of the same. Fig. 3 is atransverse section of the strap, showing its form as itissues from therolls of the rollingmill; and Fig. 4 illustrates the mode of forming thebarbs.

Similar letters of reference indicate corresponding parts.

a represents the metallic strap or band,'hav ing enlarged or re-enforcededges, as shown in' Fig. 3 of the drawn gs.

is bent serpentine, as best seen in Fig. 2 of the drawings, so as topresent crimped or corrugated surfaces and straight or unbroken top andbottom edges, as illustrated in the drawings.

b b denote the barbs pressed or struck out Ing. 1 of The body of saidstrap of the 11e-enforced edges of the strap nearly or quite at rightangles lfrom the lplane of the strap, and projecting alternately inopposite directions and respectively from the convex side of thecorrugations. j

This barbed corrugated strap I construct by first rolling out a band ofiron having enlarged or re-enforced edges, as shown in Fig. 3 ofthedrawings,then passing this band between corrugated rollers r r orcorrugated dies pressing against opposite sides of the strap, andsimultaneously bringing to bear against the two edges of the strap tworollers, s s, as illustrated in Fig. 4 ofthe drawings, the rollers r rproducing the corrugations or crimping of the strap, while the rollers ss, in conjunction with the projecting edges ofthe aforesaid rollers,press out of the reenforced edges of the strap the barbs b b. Theprojecting edges of the rollers r 1' are provided with rabbets c c ofproper size to allow portions of the enlarged edges of the strap a topass between the rollers without distorting or pressing the same.Saidrabbets are arrau ged in such relative positions as to produce bythe intervening solid projections of the rllers r 1' thebarbs b balternately at opposite edges of the strap and outward from the convexportions of the corrugations,thereby makin g them moreprominentand'effective. The described strap a is secured to the fence-post bystaples d driven into the post and striding the concave portions of thecorrugations thereof', therebypreventing the strap from slippingendwise.

Having described myinvention, what Iclaim as new, and desire to secureby Letters Patent,

l. The strap a, having enlarged or re-enforced edges and transverselycrimped or corrugated surfaces, and barbs b b, pressed or struck out ot'said re-enforced edges, substantially as set forth.

2. The strap a, formed with enlarged or re; enforced edges andwith'crimped or corrugated surfaces, and the barbs b b, pressed orstruck out of said enlarged edges at the convex side of the corrugationsand alternately in opposite directions from the plane of the strap,substantially as described and shown.

3. The within-described method of forming barbed fence-straps,consisting in rst rolling out the strap with enlarged orre-enforcededges, of two attesting Witnesses, at Syracuse, in the then corrugatingsaid band and pressing out county of 0nondaga,in the State of New York,of the enlarged edges thereof barbs standing this 11th day of January,1882.

in opposite directions from the plane of the JAMES CARPENTER. [L. S.] 5strap, substantially as described. Witnesses:

In testimony whereof I have hereunto signed C. H. DUELL, my name andafxed my seal, in the presence WM. C. RAYMOND.
